ANDREW J. BRADLEY, OF NEW YORK, N. Y.

PRINTING-STAMP.

Application filed June 10,

' To all wlzom it may concern:

Be it known that 1, ANDREW J. BRADLEY, acitize n of the United States, and'a resident of the city of New York, county of New York, and State of New York, have invented a certain new and useful Improvement in Printing-Stamps, of which the following is a specification.

My invention relates ,to hand printing stamps and has for its principal objects to facilitate adjustment of the type carrying members, to insure the accurate alinement of the characters during the operation of printing, and to attain other advantages iereinafter appearing.

The invention consists in the construction and arrangements of parts hereinafter de-- scribed and claimed.

In the accompanying drawing, which forms part of this specification, and wherein likeisymlz-ols refer to like parts wherever they occur, Figure 1 is a front elevation o l a hand printing stamp embodying my invention, portions being shown in section; F 2 is an end elevation of the device; Fig. 3 is a section on the line 3-4; of Fig. 1.

The frame of my machine comprises side members 1 and a top member 2 preferably made in a single piece. Preferably, the lower ends of the side members are connected by a thin plate 8 having a large opening in its middle portion through which the printing is effected. The middle portion of the top member of the frame has a vertically perforated boss 4. Inside of the fran'ie is a yoke 5 which conforms to the inner surface of the i thimble ortubular shell 10.

frame and has a tubular extension (5 which extends upwardly through the bore of said .boss. -This tubular extcnsionhas an elongated vertical slot 7 inits side through which projects a pin 8 that is mounted on said boss. Inside of said tubular extension is a helical spring 9 whose lower portion is inclosed in a The lower end of this helical spring bears against said pin and its upper end bears against a knob mounted on the upper end of said'tubular extension. By this arrangement, the spring normally holds said yoke up against the boss or underside of the top member of the frame, but permits said yoke to be depressed when pressure is ap )lied to said knob. Mounted on the arms 0 said yoke near the lower ends thereof is a horizontal shaft 11 whose ends project through elongated slots 12 in the side members ofthefrarne. Fixed, to or integral Specification of Letters Patent.

with this shaft is an axle or drum 13 upon which are rotatably mounted a series of similar type-wheels 14. Except for a single space 15 that is normally in the lowermost position, the periphery of each wheel is cov ered with a series of type or printing char acters, and each wheel is independently rotatable on the axle or drum.

Fixed to or. integral with each type wheel is a star wheel 16 or wheel. whose periphery is provided with V -shaped indentations equal in number to the number of cl'iaracters on the type wheel. Each of said star wheels has a radially projecting portion .17 thereon which, in the normal position of the parts, bears against a limiting stop provided therefor. As illustrated in the drawing, these limiting stops are pawls or teeth 18 formed on hand levers 19 that are fulcrumod on a cross rod or shaft 30 mounted on the arms of the yoke. parallel with the main shaft. The end of each pawl or tooth is shaped to lit the iinlentntions in its star wheel, and the hand lever is so located that its tooth or pawl can be moved into or out of cngagcment with the indentation opposite it. By reason of the sides of the indentations being inclined, the pressure of the pin thereon turns the wheel into accurate adjustment; The end of the hand. lever is arc-irate and provided with two shallow notches orindcntations 21. The yoke is provided with across-piece 22 adjacent to the inner ends of said hand levers, and this cross piece is provided with holes .or socket-s opposite the respective levers. In each socket is a spriug-presscd pin 23 having a tapering end adapted to iit the notches in said lever in eitherits outermost or innermost position. fly this arrangement, the pin serves as a means of yieldingly locking the hand lever either in engigement or out of engagement with the type wheel. In the outermost position of the locking lever, its tooth 18 is entirely clear of the indentations of the star wheel but is still in the path of the projection 17 on said star wheel and thereby serves to limit the rotation of the corresponding type wheel.

The yoke has a cross rod or shaft 24 rota- I tably mounted thereon below the cross rod upon which the locking levers are mounted. This shaft 24 is provided at its outer end with a suitable handle 26 for turning it, and

it is adapted to release and reset the locking levers in their normal position out of engagement with the type wheelsf For this purpose, the cross shaft is made of a semicylindrical section and each of the locking levers has a downwardly projecting shoulder 26 which abuts against or 18 close to the flat side of said shaft when the looking lever 1s in engagement with the type wheel. By 5 this arrangement, the cross shaft serves as an ((lUlf'Ilfl'lt or cam and the turnnu, of said cross shaft causes the lower edge thereof to j bear against the shoulder on each of the locking levers that are in engagement with their wheels and thereby tilts cacll of such levers upwardly to its normal position out of engagement with its wheel. thacross shaft might be cranked or otherwise provided with an eccentric portion to effectthe resetting of the locking lovers.

The rotation and adjustment of the type wheels may be effected by any suitable means, such, for instance, as those illustrated in applications for Letters Patent therefor executed by me of even date herewith. its illustrated in the drawiny', the end of the shaft 20 projects throtnrh the main frame and is provided with a knurled knob or handle 27 for turning it. llach type wheel (or the star wheel conn cted thereto) has a shallow notch or depression St in the inner face of its huh. 'lhc drum or axle on which the type wheels are jonrnaled is nrovldod with a series of radial holes or sock'cts 29, in each of which is a pin 30 which is pressed outwardly by means of a spring 31 in the bottom of said socket. The project .ing end of each pin is beveled or rounded and in position to register with the notch in the corresponding type wheel. Normally, each of the spring pressed pins is in engagement with its appropriate notch and thereby yieldingly looks the correspoinlingt ype wheel of such axle or drum so as to rotate therewith. locked to the frame in any position by means of its locking lever, the spring pressed looking pin in the axle or drum is free to yield automatieall so as not to interfere with the rotation of t to axle or drum. i

Mounted on the projecting end of the main shaft is an annular shell or eylindri a l indicator 33 whose periphery isprovided with characters corresponding to those on the type wheels. Fixed to the yoke is t, pointer or indicator 34 whose end overlaps the margin of said circular indicator. in the normal position. of the parts, the type wheels are yielding-1y locked to the common axle or drum, and the indicator and its pointer are arranged with reference to this normal condition; that is to say, the indicator moves with the axle and indicates the position of only those wheels which are in engagement with the axle? Journaled on the main shaft beyond the type wheels but inside of the yoke are a Obviously,

When the type wheel is positivelya l l l l l l ingri l I l l l 5 pair of arms 35 union are connected by a cross In other 36 and constitute a frame for i supporting a type inkling roll 2'37. For this purpose, the ends of said arms are. slotted i longitudinally to receive the spindles of said 1' type inking roll. baid spindles extend through the ends of the cyeholts which are mounted in perforated lugs provided therefor on said arms andhave their inner ends serew-threaded and provided with adj sting nuts 3f). Each eyeholt is provided with a helical spring it), one end of which bears against its supporting lug: and the other end of which bears against the adjusting nut, whereby said springs tend to press the type inking roll inwardly. -.,dounted on said arms alongside of the type inli'iugroll is an ink distributing roll 41 arranged to i cooperate therewith. For this purpose, the

spindles at the ends of said ink distributing roll are mounted in elongated slots and are pressed'l ysprinpgs toward thetypeinliingrolh The shaft of the type inking roll Pl?" \ided with circular enlargements or wheels 4;. arranficd to run on" circular tracks h provided therefor concentric with the type wheels. Said tracks ar so located as to keep the type nil-Lin roll clear of the wheels except at the lowermost position, nhe e tic-- premions 4-4 are formed in. said tra to permit the springs to lift the type inkingroll upwardly against the lmrerniost portious of the type wheels, is llustr: ted, the i tracks to '--;t oisegutrutal ll ks fixed to the and having curred i ches or depress sioin; in their peripl: I Suitably" mounted in path of the distrihulitr roller is an inking, pad fagainst no ch said inl; dis iibut'ing roller I normally rests.

"ion" [\s illustrated in the draw ing, this rating pad is supported upon arms 46 fastened to the yol'e or frame that reciprocates vertically in the main frame of l the machine. The ink pad is'mounted on a date t? which provided near its ends with headed pins 4-8. ach of these pins extends through the wall or a pocket provided therefor on the supporting frame, and inside of each pocket is a helical spring 49 which presses outwardl against t to head of said pin. By this arrangement, the ink pad is yieldingh' pressed against the ink distribub ller.

integral with or fixed to the frame of the type inking; roll is a segmental gear or gears 50 which mesh with a vertical rack or racks 51 provided therefor on the main frame. By this arratnrement, the downward pressure of the knob or handle 27 depresses the yoke and all ol' the parts mounted thereon, in-

-cluding the frame of the type inking: roll. l In this downward movement, the segmental l l llt) gears 50 of the frame of the type inking roll coi'iperating with said stationary racks 51 causes said frame to n nu: downwardly. in

this swingin movement, the ty )e inking roll travels along its tracks until the depressions therein permit it to rise against the type wheel and thereby ink those type that are in the lowermost or printing position, whereupon the further oscillation of said frame again carries said type inking roller against its tracks, thereby lifting it clear of the type, and swings it out of the way of the type wheels. The continuation of the downward,movement of the yoke brings said inked type into contact with the paper,

the. machine rests and thereby makes an imprint with each wheel that has been shifted from its normal position.
